This invention relates to improvements leferring` to the drzwvings7 il() indicates 65 in lifting' truclrs7 and more particularly to ythe platform or frame portion of the lifttruolrs of this character adapted -for use in iup, truck, mounted upon a plurality of lifting-one end of an automobile,y for the caster wheels ll., each of which is suitably purpose of transferring the same from place mounted in a bracket 'l2 secured to the unto place.

Secured to the lever 22 at a point near its rear end by bolts or other suitable fastening means 26 are a pair of rearwardly extending divergent handles 27 provided with hand-grips 28, conveniently arranged for use by the operator.

ounted upon the upper surface of the lever 22 are a plurality of bearing members 29 carrying a rod 30 which is positioned for sliding movement longitudinally of the lever 22, and is secured against removal from the bearing member by a Cotter-pin 3l. A compression spring 33 surrounds the slidable rod 3l between the bearing members, and is adapted to bear at one end against the forward bearing member 29, and at its other end against a` collar 34 mounted upon the slidable rod 30. A transverse rod 34 is secured to the slidable rod 30 at the rear end thereof, and is'adapted to be forced into the registering notches 2l cut in the forward edges of the downwardly extending arms of the U-shaped member, by the spring 33. Thetransverse rod 34 face of the lever 22 thus acts as a detent for maintainingr the forward end of the lever in various positions of vertical adjustment, together with the load-carried thereby. A detent releasing lever 35 is pivoted to the leverV 22 as at 36, and provided upon its for'- ward edge with a-beveled portion 37 adapted to contact with the transverse rod 34', and to force the same from engagement with the registering notches 2l upon depression of the rear end of the detent releasing lever 35, after the outer end of the lever 22 has been slightly depressed to cause the rod 34 to be lowered in the notches 2l. The rear end of the detent releasing lever is provided with an angular extending portion 3S, which may be readily actuated by the operator for the purpose of releasing the rod 34 fromthe registering notches 21. llVhen the rod 34 is released from engagement with the notches 2l, the weight carried by the arms 23 may be lowered by the operator'.

It will be seen that this lifting truck is particularly applicable for use for lifting Athe rear axle of an automobile, by reason of the forked construction of the forward end of thelifting lever, as well as the forked construction of the platform by reason of which the platform and the divergent forwardly extending armscan be readily placed in position in such a the differential housing, and when the lifting lever is depressed, the ydivergent forwardly extending arms will bear upon th rear axle housing at points located upon oppositesides of the differential housing to raise the same into elevated position. lt will be readily understood that when the lying upon the upperV truck is placed in proper position for raising the axle of an automobile, pressure may be exerted downwardly upon the handles 28 ofthe rearwardly extending arms 27, thereby causing the lever to pivot about the shaft 18, and consequently raise the axle of the automobile to the desired height. If it is desired to raise the axle still higher the lever may be still further depressed until the downwardly bent portion 39 thereof engages the floor upony which the wheels of the vehicle rest, at which time the floor will act as a fulcrum upon which the lever will pivot in rear of the normal pivot point 18, it being understood that in this case the outer end of the truclr will also be raised. In effecting this operation it may be necessary to increase the length of the outer end of the lever and this may be readily accomplished by the use of a pipe inserted over the handle portion 28 of the lever. the sliding rod 30 is free 'to move rearwardly at all times, except when acting against the detent releasing lever 35, the transverse rod 3l will be. forced into the oppositely registering slots or notches 2l as the rearward end of the lever 22 is depressed, thus automatically holding the axle of the automobile in raised position until such time as the detent releasing lever 35 is operated. When it is desired to lower the axle of the automobile to its original position the detent releasing lever 35 is operated by pressing down upon the angular portion 38, thereby bringing the beveled face 37 into contact with the transverse rod 34 and forcing the same forwardly out of engagement with the registering notches 2l, when the axle may be lowered by releasing the pressure upon the handle portions 23 of the lever.

While we have shown and described in considerable detail a specific embodiment of our invention, it is to be understood that this showing and description is illustrative only and for the purpose of rendering our invention more clear, and that we do not regard the invention as limited to the detailsv of construction illustrated or described, nor any of them, except in so far as we have included such limitation within the terms of the following claims, in which it is our intention to claim all novelty inherent in our invention broadly as well as specifically.
